Ontogenetic allometry
Most organisms undergo allometric changes in shape as they grow and mature, while others engage in metamorphosis. Even reptiles (non-avian sauropsids, e.g., crocodilians, turtles, snakes, and lizards), in which the offspring are often viewed as miniature adults, show a variety of ontogenetic changes in morphology and physiology.
